    The first of these was originally found in Germany, and subsequently in our own country, having been taken June 12th, 1823, in the New Forest in Hampshire, a spot remarkable for its rare treasures in natural history. My esteemed friend Mr. Samouelle, who took it, very kindly lent it to me to draw and describe. Megerle has thought proper to give to it the specific name pictus, “ painted.” This I somewhat regret, as pictus, “ painted,” gene- rally has an allusion to gay colours, and this is of a darkish blue. The spe- cific name cceruleus would have been much preferable, as, for an (Estrus, this colour is quite unusual. The name of pictus, when the animal it infests is known, and its place of residence in the larva state ascertained, will probably be changed for a more useful and significant one, and so indeed of the remain- ing species, obliterating my own name likewise.
